n = 23

$n = 23$ ,

p = 0.7

$p = 0.7$

Step 1

The mean of a binomial distribution is the number of trials multiplied by the probability.

μ = n \cdot p

$μ = n \cdot p$

Step 2

Fill in the known values.

μ = 23 \cdot 0.7

$μ = 23 \cdot 0.7$

Step 3

Multiply

23

$23$ by

0.7

$0.7$ .

μ = 16.1

$μ = 16.1$
